Ancient Egypt History
Ancient Egyptian civilization is considered one of the greatest civilizations on earth. generally given as 3100 BC, human activity in the Predynastic Period can be traced back many thousands of years before this date. The Sahara Desert used to be a green and fertile savannah, home to a nomadic population who hunted the wildlife they portrayed in rock drawings (petroglyphs). Archaeologists have also discovered that cattle-herders in Nabta Playa in the Western Desert built stone-circle calendars dating from 8000 BC.
